[dpdk-dev] [PATCH] drivers/qat: fix lacking memzone lookup in compression pmd

[Arek Kusztal <arkadiuszx.kusztal@intel.com>]

Because capability memzone of compression does not have lookup
call, second and subsequent devices cannot be created.

Fixes: 0e6fff16a7a2 ("drivers: add multi process handling of capabilities in QAT")
